Abstract

A high-efficiency, environment-friendly and energy-saving coal furnace includes a furnace shell, a furnace core, and a furnace grate. The energy-saving coal furnace also includes a thermal insulation layer, a flue and a chimney, and the thermal insulation layer is located between the furnace shell and the furnace core. The chimney is installed on the outer wall of the furnace shell, and the flue passes through the furnace shell, the insulation layer and the inner wall of the furnace core in turn to communicate with the upper part of the inner cavity of the furnace core, and the flue is connected with the chimney at the same time. The lower part of the smoke inlet is connected; the smoke inlet is built with a smoke baffle and a first dust removal drawer, the smoke baffle is fixed on the top wall of the smoke inlet, and the first dust removal drawer is located on the top wall of the smoke inlet. There is a gap under the baffle and between the smoke baffle; a mesh catalyst device for catalytic oxidation of harmful gases is installed at the smoke outlet on the upper part of the chimney. The utility model provides a high-efficiency, environment-friendly and energy-saving coal furnace which reduces smoke and dust discharge, improves coal utilization rate and reduces energy loss.

Description

High-efficient environment protection energy-saving furnace

Technical field

The utility model relates to a kind of coal stove, especially a kind of high-efficient environment protection energy-saving furnace.

Background technology

The widely used coal stove in the whole nation is investigated, find that it does not have strict soot emissions control device, elegant flue dust in atmosphere often contains many toxic components, harm environmental and human health impacts, and in addition, it also has the shortcomings such as coal utilizaton rate is not high, burning is abundant not.But owing to being individual use, thereby improve popularity rate in order to knock down price, and coal stove can not cause a large amount of pollutions as the use of subsection quickly, so the environmental issue people that have for coal stove lack necessary attention and correlative study.Hardly realize, take care of the pence, under the demand of the whole nation 2.2 hundred million populations, small coal also can cause large problem.

Summary of the invention

In order to overcome, the flue dust of existing coal stove discharge is many, untreated, the deficiency of not environmental protection, and the utility model provides a kind of reduces soot emissions, improve coal utilizaton rate, minimizing energy loss, high-efficient environment protection energy-saving furnace that cost is low.

The utility model solves the technical scheme that its technical problem adopts:

A kind of high-efficient environment protection energy-saving furnace, comprise stove outer covering, combustion chamber, grate, described combustion chamber is positioned at described stove outer covering, described grate is positioned at described combustion chamber bottom, described Energy-saving coal stove also comprises heat-insulation layer, flue and chimney, described heat-insulation layer is between described stove outer covering and described combustion chamber, described chimney is arranged on the outer wall of described stove outer covering, described flue is communicated with the inner chamber top of described combustion chamber through described stove outer covering, heat-insulation layer and combustion chamber inwall successively, and described flue is communicated with the mouth that enters of described chimney bottom simultaneously;

Describedly enter mouth and be built-in with flue dust baffle plate and the first dedusting drawer, described in described flue dust baffle plate is packed in, enter the roof of mouth, described the first dedusting drawer below described flue dust baffle plate and and described flue dust baffle plate between be provided with gap; The exhaust opening place on described chimney top is provided with in order to by the netted catalyst device of pernicious gas catalytic oxidation.

Further, described Energy-saving coal stove also comprises the second dedusting drawer that is positioned at described grate below, and the panel of described the second dedusting drawer is provided with ventilating opening, hinged adjustable ventilation lid on described ventilating opening.

Further, described combustion chamber inwall is uniformly-spaced furnished with vertical fin.

The beneficial effects of the utility model are mainly manifested in: reduce soot emissions, improve coal utilizaton rate, reduce energy loss, cost is low, energy-conserving and environment-protective.

Accompanying drawing explanation

Fig. 1 is the structural representation of high-efficient environment protection energy-saving furnace.

Fig. 2 is the top view of high-efficient environment protection energy-saving furnace.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

See figures.1.and.2, a kind of high-efficient environment protection energy-saving furnace, comprise stove outer covering 1, combustion chamber 2, grate 4, described combustion chamber 2 is positioned at described stove outer covering 1, described grate 4 is positioned at described combustion chamber 2 bottoms, described Energy-saving coal stove also comprises heat-insulation layer 3, flue 5 and chimney 6, described heat-insulation layer 3 is between described stove outer covering 1 and described combustion chamber 2, described chimney 6 is arranged on the outer wall of described stove outer covering 1, described flue 5 is successively through described stove outer covering 1, heat-insulation layer 3 and combustion chamber 2 inwalls are communicated with the inner chamber top of described combustion chamber 2, described flue 5 is communicated with the mouth that enters of described chimney 6 bottoms simultaneously,

Describedly enter mouth and be built-in with flue dust baffle plate 7 and the first dedusting drawer 8, described in described flue dust baffle plate 7 is packed in, enter the roof of mouth, described the first dedusting drawer 8 below described flue dust baffle plate 7 and and described flue dust baffle plate 7 between be provided with gap; The exhaust opening place on described chimney 6 tops is provided with in order to by the netted catalyst device 9 of pernicious gas catalytic oxidation.

Described Energy-saving coal stove also comprises the second dedusting drawer 10 that is positioned at described grate below, and the panel of described the second dedusting drawer 10 is provided with ventilating opening, hinged adjustable ventilation lid 11 on described ventilating opening.

Described combustion chamber 2 inwalls are uniformly-spaced furnished with vertical fin 12, the number of described fin 12 is four, coal cinder is limited in described combustion chamber 2 and can left and rightly shake, and makes the bee-hole on upper and lower coal cinder easily corresponding, and can not misplace, thereby the thermal efficiency of coal stove is improved.
